The whole cryptocurrency space is well-acquainted with the constant brawl between Vitalik Buterin, the creator of Ethereum, and Justin Sun, the Founder and CEO of Tron Foundation. This time the duo is back in the limelight due to the upcoming Ethereum hard fork, Constantinople, which is scheduled to occur on block #7080000.

Yesterday, January 9th, one of the core developers of Ethereum, Peter Szilagyi announced that the Constantinople hard fork was successful on the Rinkeby Testnet, one of the three Testnet’s of Ethereum that resembles the production chain. The successful hard fork on the Testnet comes across as an important milestone as it effectively means that the hard fork on the main chain could be smooth and successful.

Peter Szilagyi said on Twitter:

“Rinkeby #Ethereum testnet successfully forked over to Constantinople! All signers, bootnodes, faucet online and working well. Clean split between new and non-upgraded nodes (please update!).”

This announcement caught the attention of Justin Sun as he said on Twitter:

“Congrats to @VitalikButerin and one step furthur to join POS family! #TRON#TRX$TRX”

This is not the first time Sun has thrown shade at Buterin on the topic of Proof-of-Stake [PoS]. Prior to “congratulating” Buterin, Sun welcomed him to the Proof-of-Stake family. This was in response to Buterin’s tweet to Charlie Lee, the creator of Litecoin, wherein Buterin asked Lee whether he wanted to move Litecoin to PoS algorithm.

Sun’s reply to Buterin comes in the wake of Casper’s launch, which is scheduled to take place in the next couple of months. Casper is Ethereum’s Proof-of-Stake [PoS] protocol, and in an interview, Buterin claimed that Ethereum’s Proof-of-Stake protocol is much more powerful in comparison to other projects already using the PoS algorithm. The protocol would be effectively shifting Ethereum from a Proof-of-Work algorithm to a Proof-of-Stake.

Tron has been a part of the Proof-of-Stake community for a long duration now. The project has been using Delegated Proof-of-Stake algorithm since August 2017.
